From the package versions that you have installed, it seems that you have Ubuntu version focal installed, where the instructions assume the version jammy is installed.

As the instructions indicate, you need to replace jammy with whatever version you have installed.

If the problem persists, please provide all commands that you have used, including the changes to the file /etc/apt/sources.list, and the Ubuntu version that you have installed.
